Ok, what am I missing here?

[Heatwave]

Nicely done!

Success!
I just got the stem out of the fork, with no issues.
The part that was down in the fork, still looks as fresh as the day it was made back in 1898.

My guess is, that it’s been a very long time, since that part has seen the light of day.

Now, getting the rung off bolt end out is a no brainer and a replacement should be validated by the standing caveat, artist's license. Life is good.

OOOPS! Stuttered!

Glad you had success Marty. I gave it a modest try but was worried I’d wind up breaking something irreplaceable. I know the bike is in the right hands!

Thanks, guys!
I figured that thread would be some odd proprietary size, but it turns out to be good ol 1/4”-20!
Nice!

Maybe 5/16"?

No, it’s a smaller diameter than a typical stem bolt, to accommodate having to pass through the handlebar clamping bolt.
Which I’m sure is why it was broken.
That was probably a common malaise with that Hussey type system, and one of the reasons why it eventually fell out of favor in the industry.
1/4”-20 thread pitch is a common hardware store bolt size, so a replacement bolt is readily available, but the hex head is most likely of a different shape and size.
So, I’ll still need to have a bolt made and nickel plated.
But at least I’m heading it the right direction on it.
Now, to find an example of what that bolt head looked like on an 1898/99 Schwinn/World bicycle.
Anybody got a picture of a 1898/99 Schwinn stem?
This picture sure looks like it, but I have no idea, if that is a Schwinn stem, or if it’s original to that combo?

If it is, then a regular hardware store bolt may actually work, with just a touch of nickel on it?

That certainly looks like it would fill the bill. My question is that an integral washer? If so still no big deal just sweat a washer on and have it plated.

Mc Fadden Dale Hardware for a long 1/4" Grade 8 bolt, maybe even an Allen Head bolt, then stop at Johhny True Torch to weld a hex nut on the top with your desired wrench size. WaLa! You have a brand new 1898 Schwinn part. Shawn has the correct way of adding a flanged washer if that is required.

Ok, I went over to McFaddendale Hardware, and picked up a nice Grade 8, 6”x1/4”-20 threads per inch bolt, that worked out perfect!

There was a telltale mark of a shoulder bolt on the 1898 Schwinn stem.

And as luck would have it, the hardware store grade 8 bolt had the exact same size shoulder on it.

The thread zone was a bit lacking for this purpose, so I cut a few more threads into it.

And walla!

Now, off to the metal refinishing shop to get nickel plated, and one replacement expander bolt for the 1898/99 Schwinn/World stem, handled!
